Core Features

1. Rapid swelling upon contact with water, longitudinal water blocking: After contacting moisture, SAP resin quickly absorbs water and swells to form a gel, sealing the gaps inside the cable core, preventing water from spreading longitudinally along the optical cable and protecting optical fibers from water erosion. The gel boasts excellent water retention and is not prone to leakage.

2. Flexible texture and good wrapping conformity: Soft and easy to bend, it can tightly wrap the cable core and adapt to high-speed cable forming longitudinal wrapping equipment. It produces little powder and resists breakage during bending, delivering superior processability.

3. Good thermal stability: It can withstand short-term high temperatures during the sheath extrusion process, will not fail prematurely under heat, and does not decompose to contaminate internal cable components.

4. Excellent chemical compatibility: It is neutral and non-corrosive to optical fibers, PBT loose tubes, FRP, PP wrapping tapes, stainless steel armor and other materials. It is mildew-resistant and resistant to microbial attack, maintaining long-term stability in humid underground environments. Featuring a dry structure with no filling grease, it enables clean and simple joint construction.

5. Non-metallic insulating material: Non-conductive and free of electromagnetic induction, it will not interfere with optical signal transmission.
